"The next version from Megasthenes comes in Pliny. Pliny (IV.22)2 touches on the Gangaridai after making an observation about the Ganges in mid-career: "...it flows out with a gentle current, being at the narrowest eight miles, and on the average a hundred stadia in breadth, and never of less depth than twenty paces (one hundred feet) in the final part of its course, which is through the country of the Gāngārides. The royal city of the Calingae is called Parthalis. Over their king 60,000 foot soldiers, 1,000 horsemen, 700 elephants keep watch and ward 'in procinct of war'.""
